Each of the light source units has a heatsink, a light emitting element substrate attached to the heatsink, light emitting elements mounted on the substrate. The light source device also includes a plurality of cooling fans such that they face cooling fins of the heatsinks. The light source units are arranged side by side in a direction orthogonal to the extending direction of the cooling fins of the heatsinks, the cooling fans are arranged side by side in the same direction as the arrangement direction of the light source units, and a partition plate that extends substantially parallel to the extending direction of the cooling fins and toward the cooling fins is disposed between each two adjacent cooling fans.
